ENCLOSURE BELLEFONTE NUCLEAR PLANT UNITS 1 AND 2 IMPROPER USE OF ALTERNATE ANALYSIS FOR ELBOLETS NCR BLN BLP 8231 BLRD-50-438/82-78, BLRD-50-439/82-72 10 CFR 50.55(e)
SECOND INTERIM REPORT Description of Deficiency During design review, it was discovered that Bellefonte alternate analysis calculation BLN-KC-D053-11, which concerns the Component Cooling System, contains an elbolet. The Ballefonte Nuclear Plant Alternate Criteria for Piping Ar.alysis and Support (CEB 76-11), which is the basis for this calculation, excludes any component from its scope which is not specifically listed in appendix E (Stress Intensification Factors).
Elbolets are not listed.
Interim Progress The determination has been made that elbolet installations must be rigorously analyzed. All cases where piping containing an-~elbolet were qualified by the Bellefonte Nuclear Plant Alternate Criteria for Piping Analysis and Support are being identified. Once identified, ellolets involved will be either eliminated or included in rigorous analysis.
